I'd like to remote control my stereo with the Pi.
I followed several tutorials and I managed to record an lircd.conf for my IR remote.
The IR receiver is connected to pin 18 (between GND and RXD).
Sending IR commands doesn't work but I managed to run the command "sudo irsend SEND_ONCE sharp POWER" without any errors. What pin do I have to connect the IR LED to? I'm using this setup (except the Pi pins are different ones). Instead of an IR LED I'm currently using a visible one to check if there is a signal at all. I checked the transistor circuit by connecting the signal pin to GND and 3V, this works as well. But still the LED stays dark for any pin when running the irsend command.
